Own extractor is very necessary in beekeeping.
Don't even think to do own..
If you find used, half price, that would be good.
However, when you have basic skills and tools, it is easier to nurse 5 hives than 3 hives.
If one dies from 3, it is 33%
when hive is full of nectar and capped honey, bees slown down working if you cannot ectract honey and arrange new room for nextar. You may loose easily extractor price only with this system.
I had a hive on balance. It brought more weight 3,5 kg a day. Bees hung in cluster on walls because hive was full. I took capped honey away and gove 3 boxes empty combs. Next day the hive brought 7 kg .
It was raspberry flow.
At same year another hive on balance brought 50kg in 7 days. Every day 7,5 kg. If you are able to catch these flows, it is best what you see in bee nursing. Total yield was 170 kg.
